Hi;

For reading sources for acquire, I do:

AcquireApis := [];
Include(AcquireApis, ieaTwain);
MIO.AcquireParams.FillListWithSources(meSources.Items, AcquireApis);

My lists are filled with TWAIN but also with WIA, why is that?. Then If I select WIA option I may not work and user does not uderstand why.

Also, there are some cases that TWAIN source does nothing (when doing acquire) and I have to kill the application!!!, but the WIA option works.

I can't understand ... Somebody can clarify me?

Thank you very much.

Hi

What you will find is that the driver listed as WIA-HP is actually using a Twain driver. Presumably there is also a WIA driver, and this a Twain interface, that is redirected to the WIA driver.
